Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
The answer to this question would be: inhalation or intranasal
Aerosols and sprays will make a liquid substance spread in the air. This method is used to deliver the drug by inhalation. When the air is inhaled, the drugs will enter the alveolus of the lungs and diffuse into the capillary vessel and then delivered into the body.
Note that this method is different to intranasal. Inhaler used by mouth and the target is lungs. Intranasal is used by the nose and target is the nasal mucosa. Spray mostly used for intranasal since it won't reach long distance as aerosol do.
The function of the somatic nervous system includes all nerves controlling the muscular system and external sensory receptors.
Chemical and gaseous exchange takes place only across capillary walls
Sorry for the late answer but I hope that's still help !
Answer: Lotion
The type of preparation that must be patted onto the skin rather
than rubbed in is lotion. The reason why it should be patted is to prevent increase
circulation and itching. Lotions are water base and for external use only to
soothe or protect the skin from dryness.
